PLOW.

Specification of Letters Patent.

Patented Oct. 15,1912.

Application filed June 24, 1910, Serial No. 568,712.

To all whom it may concern.

Be it known that I, Srcrnno PETERSON, a citizenof the United States,residing at Lost Springs, in the county of Marion and State of Kansas,have invented certain new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates to plows, and particularly to a. form ofconstruction therefor in which a share consisting of two detachablesections, is employed.

The object of the invention is to provide a form .of plow share,consisting of two separate scctions, one of which is provided 7 with theusual cutting edge and an integral point, whereby the front sectionwhich carries the said cutting edge andpoint may be detachedfrom therearsection so, that it may besh'arpened, or otherwise repaired, or

in order to-replaceth' front section With a new section.

According to the present1nvent1on,'the

two sections of the plow share are each pro-' vided with a landsideportion, the-said portions being adapted to be placed in alinement' andlocked'together by an improved form of fastening means, and furthermeans are provided for loc-klng the two sections in such a manner as toprevent the sliding movement of one sect-ion theother. I 4 s F 0111a,full understanding of the present invention, reference is to he had tothe following description and the accompanying drawings,in which Figure1 is a bottom plan view of a plow share constructed of two (detachablesections according to the present invention, certain with reference toof the parts being shown in section; Fig. 2-

is a sectionalwviem taken on the line 2 2 of Fig. 1; Fig. 3 is afragmentary elevation looking toward thermostat of the plow formedbeveled, as will be seen particularly the socket 15'.

on reference to Figs. 2,and 3, and this beveled edge engages in alongitudinal groove 13 which is formed in the rear edge of the frontsection 12. It is contemplated that the rear section 10 of the sharewill have the usual moldboard secured thereto. The front section 12carries an integral point, which is the front projection on the'landsideedge of the cutting edge.

On the under side of the rear section 10 of the share, and adjacent tothe front edge thereof, a pair of sockets 15 and 15 are provided,the-socket 15 being formedwith outwardly projecting locking extensions16, the rear portions 17 of which are preferably integrally, orotherwise formed, with the adjacent member 15. On the under side of thefront portion 12 of the share, at the rear edge of the latter, and inpositions opposite to the positions occupied by the sockets l5 and15,are disposed two socket members 18- and 18. The locking. extensions16. be

fore referred to are made of such a length that they will engageopposite sides of the socket member18 when the two sections 10 and 12are mounted in their proper relative positions so that the socket 1 8 isopposite The plow share formed in two' sections ac cording to thepresent inventiom-is provided with-the usual landside, the sameconsisting of the section 21, which may be formed integrally with therear section 10-0f the share,

and the section 24, which may be formed integrally with the frontsection-12 of the share. The portion 21 of the landside is formed nearits forward portion with a groove 22 in its outer side, this groovebeingadapted to receive a tongue 23 which corresponds in shape to thegroove, and is formed integrally with the landside portion 24 of thefront section 12 and projects'rearwardly therefrom. A screw 25 passesthrough the landside portion 21 and through the tongue 23, so as tosecurely hold the tongue in the groove, this being apparent vfrom Figs.'1 and 3.

Headed screws 26 pass through the sockets 15 and 15 and are adapted toengage in threaded openings in the socketimembers 18- and-18, disposedopposite to the sockets 15,

and 15', whereby the sections 10 and 1.2 of the share may beoppositelyconnected to gether. The engaging sockets 15 and 18, audio and18, are designed to prevent any oppositevsliding movement of the from=1,

tion 12 along the beveled edge 11 ofthe rearv pairing purposes.

Having thus described the invention, what 1s claimed as new 1s:

1. In a plow, 1n comblnatlon, a share consisting of two detachablesect-ions, the front edge portion of the rear section of the share beingbeveled said section being provided with a landside portion, the frontsection having a cutting edge and being formed with a landside portionadapted to be placed in alinelnent with the landside portion of i thesaid rear section, said front section be- 'landside portion of said ingprovided on its side opposite to the cutting edge with a groove adaptedto'receive the beveled edge of sai i rear section, the

,fr ont section of the share being provided with a tongue and the landside portion of the rear section of the share being provided with agroove in its .side adapted to receive said tongue, means I forfastenin'g said tongue in the groove, a socket arranged on the underside of the rear section of the share adjacent the beveled edge thereof,a socket arranged ,on the under side of the front section of the shareadjacent the rear grooved edge thereof, said two sockets being adaptedto contact with each other, fastening means passing through both of saidsockets, and extensions formed on said first named socket andextending-beyond the frontedge of the rear section of said share so asto engage the sides of said Copies of this patent may be obtained forfive cents each, by addressing the Commissioner of Ifaten'ts:

second socket andithe lower side of the front sectlon of the share. 2.In a plow, zin: combination,a share consisting of two detachablesections, the front ing provided on its side opposite to the cuttingedge'with a groove adapted to receive the beveled edge of said rearsection, the

.landside portion of said front section of the share being provided witha tongue and the landside portion of said rear section of the sh'arebeing provided with a groove in its side adapted to receive said tongue,a bolt passing through the wall of the land-side portion of said rearsection and through said tongue adapted to fasten the latter in thegroove, a pair of sockets arranged on the under'si'de of said rearsection of the share at the beveled edge thereof, a pair of socketsarranged on the underside'of said front section of the share at the reargrooved edge thereof and adapted to connect respectively with said firstnamed socketsfa screw pass-' 1 ing through each pair of sockets andadapted to fasten the same together, and a pair of extensions formed onone of said sockets,

one to each side thereof,- said extensions bei ing adaptedto-engage withthe correspond.

ing socket on the front section of said share and to also engage theunder side of said front section.

In testimony whereof I aflix my signature in presence of two witnesses.
